It's not always true that any variable can be taken as the basic and free variables, as you said. Variables corresponding to pivot columns should be taken as basic variables, and the other variables are taken as free variables.
@@joudrodiak4681 studying 6h straight at the middle of the night is not a good way to study Buddy. I'm probably failing the subject too since I cannot seem to grasp it,but definitely try and study a little bit at a time while focused.
Hello, I don't really get why x3 should be free, I do see that it's not a pivot column and therefore free, but what is the logic behind that? Is it that both x1 and x2 is dependent on x3 that is telling us that it should be free? Would be nice with a small explanation. Thanks for your videos btw! Cheers!
Ephesians 2:8-9 (8) For by grace that we are saved through Faith and that not of yourselves, it is a gift from GOD, (9) not by works that no one may boast. This Bible verse only tells us that to be able to rest in CHRIST JESUS for eternity, one must put his/her faith in HIM, I know not who need this but I would leave it here
